Claims.

My invention relates generally to structures presenting openings as forexample, and more particularly, in the case of hatches of refrigeratorcars, provided with closures mounted to be 5 moved into and out ofclosing position, and which it is desired be locked either in closedposition or partially open position, as for instance to provide for theventilation of the space controlled by the closure.

My objects are to provide means for so locking the closures; to providemeans for locking the closures in different partially open positions;and to accomplish these purposes by a simple, inexpensive, durable, andpositively functioning construction.

Referring to the accompanying drawing: Figure 1 is a fragmentary View,in sectional elevation, of the hatch of a refrigerator car having aclosure with means embodying my invention for locking it in diiferentpositions.

Figure 2 is a plan view of a retainer or casing for a bolt forming apart of said means.

Figure 3 is a view in side elevation of the retainer or casing shown inFig. 2, with the bolt in place therein.

Figure 4 is an end view of the retainer or casing.

Figure 5 is an enlarged sectional view taken at the line 5 on Fig. 3 andviewed in the direction of the arrow; and

Figure 6, an enlarged fragmentary sectional view taken at the line 6 onFig. 3 and viewed in the direction of the arrow.

Referring to the construction shown wherein I have illustrated myinvention as provided for the locking of a hatch cover, of arefrigerator car, in different positions, a portion of the roof of thecar is shown at 'I andthe hatch thereof which opens into the icecompartment and as commonly provided, at S. The cover for the hatch 8 isshown at 9 and is provided with the usual depending plug portion Illwhich ts the hatch 8 in sealed engagement therewith when the cover isclosed, the cover being hinged along one edge as represented at Il to abracket I2 secured to the roof of the car adjacent the hatch therebyadapting the cover to be swung from closed position represented by thedotted lines at the right-hand side of Fig. 1 to the full open positionshown by the dotted lines at the left-hand side of Fig. 1.

Secured to the top surface of the free edge portion of the cover 9, asby bolts I3, is a casting I4 formed with spaced apart jaws l5 and i6having alining openings I1 and I8.

The casting It is also formed with a tubular portion I9 having anopening 26 extending lengthwise entirely therethrough and in line with,and opening into, the opening I8, the upper wall of the opening 2libeing longitudinally slotted as shown at 2l from a point adjacent thejaw I6 entirely through the opposite end of the tubular 5 portion I9.

A pair of spaced ribs 22 and 23 rise from the body of the casting I4between the ends of the tubular portion I9 to provide .an upwardlyopening recess 24 therebetween which extends through 10 the wall of theopening 20 as shown.

Movable lengthwise in the openings I1, I8 and i9 is a bolt having acylindrical portion 25 and held against accidental separation from thecasting Ill which forms a bolt casing or retainer, by a 16 stop 26 shownas a rivet secured to the casing. The bolt referred to has a handleportion 21 shown as extending from the body portion 25 at a right anglethereto `and adapted to enter the space 24 between the ribs 22 and 23 asshown 20 when the bolt is projected to the position shown in Figs. 1 and5 in which it extends ,at one end of its cylindrical portion 25 into theopenings I'I and I8.

Fulcrumed at its lower end to the roof I of 25 the car, as indicated at28, is an upwardly extending lock lever 29 shown as having alongitudinal series of bolt-receiving holes 30 and adapted to extendinto the space between the jaws I5 and IG for engagement by the boltabove 30 described which may enter the one of the holes 3l) inregistration therewith.

The lowerrnost one of the holes 30, preferably slightly elongated, is sopositioned that it registers with the bolt when the cover is swung tolower- 35 most horizontal closed position as shown by the dotted linesat the right-hand side of Fig. 1, thus permitting of the locking of thecover in closed position. The others of these holes are provided topermit the cover to be locked by the bolt in va- 40 rious degrees, asdesired, of partially open position, as for example as shown by the fulllines in Fig. 1 wherein the bolt extends into the uppermost one of theholes 3B for locking the cover in the extreme partially open position.45

When the cover has been locked in the desired position stated, lockingmeans may be sealed against release as by means of a so-called car sealsuch as the common form of strap car seal shown at 3l the strap portionof which is threaded 50 through vholes 32 in the ribs 22 and 23 and aregistering hole 33 in the handle portion 21 of the bolt. Other sealingmeans for the lock may be used as for example a seal pin 25a insertedinto an opening in the protruding end of the bolt. 55

In assembling the bolt and casing the bolt is introduced at the endthereof farthest from the handle 21 into the outer end of the opening 20and slid along the member I9 to a position in which the other end of thebolt clears the entering end of the opening 20 and the stop 26 thenapplied to` position, the latter being so positioned that the bolt maybe withdrawn from the space between the jaws I and i6 to permit of themanipulation of the lever 29.

While I have illustrated and described a particular constructionembodying my invention, I do not wish to be understood as intending tolimit it thereto, as the same may be variously modified and alteredwithout departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is:

1. A device adapted to be mounted on a closure in cooperation with alock lever, the device comprising an'attaching plate, spaced jaws on theplate open at one end to receive the lock lever, a tubular portion onsaid plate having one end open through one of said jaws, and a movablesecuring bolt for said lock lever mounted by said tubular portionadapted for projection through sai-d opening, the last mentioned jawthus functioning dually in the guidance of both the lever and thesecuring bolt.

2, A device adapted to be mounted on a closure in cooperation with alock lever, the device comprising a one piece retainer, spaced jaws onthe retainer open at one end to receive the lock lever, a tubularportion on said retainer having one end integral with one of said jaws,the latter jaw having an 4opening therethrough, and a movable securingbolt for said lock lever adapted for projection through said opening,said latter jaw thus functioning dually in the guidance of both thelever and the securing bolt.

3. A device adapted to be mounted on a closure in cooperation with alock lever, said `device comprising a. plate having an attachingportion, spaced jaws on the plate open at one end to receive a locklever, a tubular portion on said plate adjacent the innermost jaw, thelatter jaw having an opening therethrough, said tubular portion having alongitudinal slot initially open at the end of the tubular portionremote to the jaws, a securing bolt slidable in said tubular portion forprojection through said opening to engage the lock lever, said latterjaw thus functioning dually in the guidance of both the lever and thesecuring bolt, operating means on the bolt extending through said slot,and means extending into' the bore of the tubular portion to preventdisengagement of the bolt therefrom.

4. A device adapted to be mounted on a closure in cooperation with alock lever, a device comprising a plate having an attaching portion,spaced jaws on the plate open at one end to receive a lock lever, atubular portion on said plate adjacent the innermost jaw, the latter jawhaving an opening therethrough, said tubular portion having alongitudinal slot initially open at the end of the tubular portionremote to the jaws, a securing bolt slidable in said tubular por-v tionfor projection through said opening to engage the lock lever, saidlatter jaw thus functioning dually in the guidance of both the lever andthe securing bolt, operating means .on the bolt extending through saidslot, means extending into k the bore of the tubular portion to preventdisengagement of the bolt therefrom, said slot being open intermediateits end whereby the bolt may be turned, and means adjacent the openingof the slot coacting with the operating means to prevent sliding of thebolt.

5. A bolt device comprising a member having a bore to receive a boltprovided with a handle extending laterally therefrom, the wall 0f saidbore at one end of the device having a slot eX- tending lengthwisethereof through said end of the device to receive said handle uponintroducing the bolt into the slotted end of the bore, said bore havinga slot traversing said bore at the other end of said device forreceiving an element E' to be interlocked with said bolt, the device atone end of the bore having a part functioning dually in the guidance ofboth said element and the securing bolt.
